what if your number of text input fields is dynamic?

[snod0g]

as far as i know jsf/ajax4jsf requires you to have every form field on your page have a private bean property associated with it.

for example every text input field would have a private String on the class associated with that page.

what if your number of text fields is dynamic? ie you want to have it do a web service call which returns some data that lets you know how many text fields there are.

the only thing i can think of is maybe an array of strings can be populated and then somehow use JSF or JSTL to iterate through that array and draw text fields and labels?

some example code would be great, thanks.

Look for the documentation on ui:repeat for facelets and a4j:repeat from Ajax4jsf

i'm not using facelets, im just using the JSF reference implementation

[snod0g]

do u know of an example of using ui:repeat to render some input fields that shows both the JSP code and the Java code?

i am using jboss 4.0.5 (tomcat 5.5) with JSF 1.1 reference implementation.

can i use facelets with this setup? they recommend using JSF RI 1.2 in the readme but i wonder what will happen if I use 1.1? I don't think I can use JSF 1.2 in Jboss 4.0.5 because tomcat 5.5 doesn support java servlet 2.5 and jsp 2.1 as required by jsf 1.2: https://javaserverfaces.dev.java.net/nonav/rlnotes/1.2_04/releasenotes.html

facelets do not work with JSP at all. So, if you use facelets, supporting java servlet 2.5 and jsp 2.1 is not required.
Ask for right configuration on jboss seam forum.

If I understand your question, you can back the text inputs to a map in the backing bean:

bean.java

...
private HashMap<String,String> map = new HashMap<String,String>();

public HashMap getMap() {
 ...
}

public void setMap(HashMap) {
 ...
}
..

so then you input fields will be like:

<h:inputText value="#{bean.map[someIndex]}" />

Anyway, I recommend checking out seam with facelets rather then jsp

hope that helps,
